...we’ve learnt that his manager commits fraud, that manager commits perjury”... 5xWhy leads to the question “Why are managers under such pressure”, the answer is two-fold: “They want to have a family and a cost of living is high, and they’re ready to die themselves at their desk to make enough money, so they actually care more about the lives of others than their own, which is ironic”, the other is “Because Boeing is fundamentally on older tech than Airbus, so no matter how they press the lemon, they can only squeeze that much.” See, Boeing was built before Airbus. Airbus benefited from starting at the electronics age, with lessons learnt from Boeing. It had an impact on the design: Airbus is fly-by-wire, Boeing isn’t. Probably all the tech stack of Airbus slightly newer, with slightly newer management methods too (legacy is a curse to get rid of) and easier for them to iterate and upgrade. That alone could explain why each generation of Boeing plane was rushed to the market, including the explosive batteries circa 2010, the broken airframes by Ducommon for 4.7% planes, helped by FAA delegating self-certification of their planes to Boeing itself, and the coup de grace, planes that literally want to aim for the ground in 2019, all of that in 8 years. Ironically they’ve bought McDonnell 20 years ago which was pro at sneaking past FAA regulations. Maybe they’ve “learnt” from MD. But there are so many others in hiding that we have to throw away the last 20 years of engineering: For example the MCAS had only 1 processor, when all other systems are required to have 2 to 3. We can’t risk 100 lives for each lie Boeing did in the past 20 years. I’m not sure there is actually a lot to learn that we didn’t know: The FAA shouldn’t delegate Boeing certification to Boeing, managers should not ask employees to drill new holes when the original holes were drilled 3 inches apart and don’t fit, because it endangers the structural integrity, one should not use a hammer to change the shape of the airframe by a full inch, collapsing the I-beam by folding it, compromising the structural integrity, they shouldn’t have lied about changing the features of the MCAS, and the market should have been nicer with their revenue. Every bankruptcy is sad and unfair. It’s disheartening to fire people who certainly have given all they could to compete with a better competitor. But it’s time to cut the loss, because their failure is ingrained in their engineering and management, and is costing real deaths in real world.
